High performance concrete bridges
introduction
HPC is made with some basic ingredients but has totally different microstructure than ordinary concrete
HPC is an engineered concrete obtained through a careful selection
The low water/binder ratio of HPC that is its universal characteristics
It has very dense microstructure having a very fine and more or less well connected capillary system
Dense microstructure of HPC makes the migration of aggressive environmental conditions.

HIGH PERFORMANCE CONCRETE USING FUMED SILICA

INTRODUCTION
High performance concrete is a concrete having low water binder ratio. A value of 0.4 is suggested as boundary between usual concrete and high performance concrete.
It has high strength and durability. For high durability low permeability is required and to reduce permeability silica fume is used

Abstract
This study aims to determine the influence of the content of water and cement, water binder ratio, and
the replacement of fly ash and silica fume on the durability of high performance concrete (HPC) by using
artificial neural networks (ANNs). To achieve this, an ANNs model is developed to predict the durability of
high performance concrete which is expressed in terms of chloride ions permeability in accordance with
ASTM C1202-97 or AASHTO T277. The model is developed, trained and tested by using 86 data ....etc

Behavior of instrumented prestressed high performance concrete bridge girders
A comprehensive monitoring of the behavior of four prestressed high performance concrete (HPC) bridge
girders, with higher compressive strength, during construction and while in-service, is discussed in this article. The instrumentation and monitoring of a group of four girders during the process of casting operation, after construction and under the conditions and influences of traffic and thermal loads, as well as under controlled load conditions is done.Th ....etc

ABSTRACT

Objective:
To study the effect of fibres on the strength and behaviour of ultra high performance concrete (UHPC)wall panels under one way and two way in plane action.

Methodology:
The UHPC mix already developed (taken from literature) studied in detail with regard to its fresh and hardened properties and durability. Wall panels of size 750x750x35 mm are to be cast with different aspect ratio and volume fraction of fibres for testing under one way in plane action and two way in plane action. The specimen ....etc
